COMPOSITE GOLF CLUB HEAD WITH IMPROVED SOUND
First Claim
1. A golf club head comprising:
- a striking face placed at a frontal portion of said golf club head; and
a body portion having a crown and a sole, attached to an aft portion of said striking face;
wherein at least one of said striking face, said crown, or said sole is formed out of a low-damping composite;
said low-damping composite has a damping loss factor of less than about 0.02.

Abstract
A composite golf club head with improved sound characteristics is disclosed herein. More specifically, the present invention relates to a golf club head that utilizes a unique composite type material having a low damping coefficient; creating more discretionary weight to optimize performance without comprising the sound of the golf club head. Depending on the amount of discretionary weight desired, the present invention could replace parts of the crown, the sole, the striking face, or even all three of the above referenced components with a low-damping composite material to improve the performance. The low-damping composite material used in accordance with the current invention may generally have a damping loss factor (η) of less than about 0.02.
